Astroscale UK (ASUK) is seeking a technically strong Guidance, Navigation, and Control (GNC) Engineer to join our UK-based GNC Algorithm and Simulation team, a key part of our Algorithms and Software Group. The successful candidate will play an important role in the design, development, verification and deployment of GNC algorithms and software for our spacecraft systems, working across the full development lifecycle from early concept and algorithm design through simulation, testing, integration and on-orbit operations.
Our mission is to capture and remove uncontrolled space debris, paving the way for innovative technologies that safeguard the long-term sustainability of orbital operations. You’ll contribute directly to this mission by developing the guidance, navigation and control capabilities required for rendezvous and proximity operations, including autonomous navigation, relative pose estimation, guidance, control and the simulation environment required to demonstrate it.
This is an opportunity to work on GNC technologies at the forefront of in-orbit servicing and active debris removal, where the algorithms you develop and the simulations you build will contribute to real spacecraft missions. You will be encouraged to take ownership of challenging technical problems, develop innovative solutions and collaborate with a multidisciplinary, international team to turn advanced GNC concepts into reliable flight-ready systems.

About Astroscale
Astroscale is the global leader in on-orbit servicing, dedicated to the secure and sustainable development of space. The company delivers a variety of innovative and scalable on-orbit servicing solutions, including life extension, refurbishment, upgrades, in-situ space situational awareness, end-of-life, and active debris removal. Since its first successful launch in March 2021, Astroscale has proven rendezvous and proximity operations technologies in orbit during the ELSA-d and ADRAS-J missions. Astroscale spacecraft have been selected for pioneering missions with JAXA, the U.S. Space Force, the European Space Agency, the UK Space Agency, and Eutelsat. As more satellite operators adopt on-orbit servicing to routinely inspect, relocate, remove, and extend the life of spacecraft, the potential of a circular space economy — and a future of no waste in space — is being unlocked. Headquartered in Japan, Astroscale has a global presence with subsidiaries in the United Kingdom, the United States, France, and Israel. Find out more about Astroscale at www.astroscale.com.
